Ability to "phase" through solid matter like the X-Men's Kitty Pryde or the Avengers' Vision -- except that to activate it, he/she has to be moving at above a certain speed when he/she reaches the solid surface, and that speed is beyond the reach of his/her muscles. This means he/she has to be thrown by someone with super-strength, or dive off a cliff or building at least three stories high (and then sort of "swim" through the ground). Well, or crash a car into the surface. The car itself, though, is too much mass for him/her to take along into intangibility (he/she is able to phase some things with him/her, starting with clothing, but there are mass limitations).
Fun fact: this actually came to me as I was waking up this morning.

Big Brother is watching you. And damn, you are so bloody BORING.
